A refrigeration panel system is provided having a first panel and a second panel. Each of the panels has an insulated core and a top and bottom metal skin attached to the insulation core. The first panel includes a groove at an end of the insulation core of the first panel. The second panel includes a tongue formed on the end of the insulation core of the second panel. The groove is adapted to receive and surround the tongue. Interlocking engagement members are disposed inside the groove and along the tongue, and provide a biasing force that pulls and holds the end of the first panel and the end of the second panel together, after the tongue is inserted into the groove and pushed past a predetermined point.
